This study aims to analyze the prevalence and likelihood of overweight, obesity, and elevated body mass index (BMI) among sexual minority men (i.e., men who have sex with men [MSM], men who have sex with men and women [MSMW], and all sexual minority men), using men who have sex with women (MSW) as the reference group. Studies reporting mean BMIs or prevalence or likelihood of obesity, overweight, or elevated BMI categorized by sexual orientation were included. Data were pooled and analyzed to report mean differences (MDs) of BMIs, prevalence rates, odds ratios (ORs), and their respective 95% confidence intervals (CIs). Forty-three studies were included, with a median of 26,507 participants (median 3.37% sexual minority men). The respective mean overweight, obesity, and elevated BMI prevalence rates among MSM (36%, 23%, and 39%) and MSMW (33%, 27%, and 47%) were lower than those of MSW (44%, 26%, and 55%). This finding was consistent with a significantly lower BMI (MD -1.50 [-1.93, -1.08] kg/m) and a decreased likelihood of overweight (OR 0.75 [0.64, 0.88]) and obesity (OR 0.84 [0.78, 0.90]). Sexual minority men present with a lower prevalence and likelihood of obesity and overweight than their heterosexual counterparts. The obesity paradox-a sustained catabolic state presenting with lower BMI-is a feasible explanation for this phenomenon, although further research exploring paradoxical cardiovascular findings is granted.
本研究旨在分析男男性接触者（即男男性接触者[MSM]、男男性接触者和女性[MSMW]以及所有男男性接触者）中超重、肥胖和体重指数（BMI）升高的流行率和可能性，并以与女性发生性行为的男性（MSW）为参照组。本研究纳入了报告根据性取向分类的平均 BMI 或肥胖、超重或 BMI 升高流行率或可能性的研究。对数据进行汇总和分析，以报告 BMI 的平均差异（MD）、肥胖、超重或 BMI 升高的流行率、比值比（OR）及其各自的 95%置信区间（CI）。共纳入 43 项研究，中位数为 26507 名参与者（中位数为 3.37%的男男性接触者）。MSM（36%、23%和 39%）和 MSMW（33%、27%和 47%）的超重、肥胖和 BMI 升高的相应流行率低于 MSW（44%、26%和 55%）。这一发现与 BMI 显著降低（MD-1.50[-1.93，-1.08]kg/m）以及超重（OR 0.75[0.64，0.88]）和肥胖（OR 0.84[0.78，0.90]）的可能性降低一致。男男性接触者的肥胖和超重流行率和可能性低于异性恋者。肥胖悖论——一种持续的分解代谢状态，表现为较低的 BMI——是对这一现象的一种可行解释，尽管进一步研究探索悖论性的心血管发现是有必要的。
